A Comparison Between Age Determinations of the Antarctic Fish Notothenia gibberifrons Lönnberg Using Scales and Otoliths R. Coggan (United Kingdom), K. Skora (Poland), A. Murray and M. White (United Kingdom)
Resumen:
Scales and otoliths were collected from 304 specimens of the Antarctic fish Notothenia gibberifrons. When interpreted separately, only 25% of scale and otolith readings agreed. When a scale and otolith from a single simultaneously, 75% of readings agreed. of otolith readings changed between specimen were interpreted 60% of scale readings and 30% separate and simultaneous interpretations.

Hydrological Conditions and Peculiarities of Glassfish Distribution on the South Georgia Island Shelf in 1986 1987 V.N. Shnar and V.I. Shlibanov (USSR)
Resumen:
Some peculiarities of spatial and temporal variability of the glassfish distribution on the South Georgia Island shelf relative to environmental conditions have been revealed from summarizing and analysis of hydrographic and commercial fishery and biological data for 1986-1987.

Growth and Natural Mortality of Yellowfin Notothenia Patagonotothen guntheri shagensis from Shag Rocks Shelf V.I. Shlibanov (USSR)
Resumen:
Regularities of growth are established from the data of age determinations and analysis of yellowfin notothenia length-weight composition, mathematical description of length-weight dependence and parameters of Bertalanffy equation are given. Natural mortality coefficient, M, calculated by six various methods ranged from 0.63 to 1.06. With mean value of M, age and length at optimum exploitation Read More

On Ageing Technique for Icefish (champsocephalus gunnari Lönnberg 1905) from South Georgia Island Shelf Zh.A. Frolkina (USSR)
Resumen:
Radii of annual elements were calculated on the basis of studying C. gunnari length frequency distribution simultaneously with the measuring of otolith radii of fish taken in July-September. This was done using specimens from strictly’ defined age groups. These radii measurements suggest an adjustment to age determination of fish longer than 30 cm with an enlarged otolith centre. An age-length Read More

On Assessment of Bertalanffy Growth Equation Parameters and Instantaneous Natural Mortality Rate on South Georgia Icefish Zh.A. Frolkina and R.S. Dorovskikh (USSR)
Resumen:
Analysis and summarizing extensive materials on size-weight and size-age composition of South Georgia icefish for 1965-1987 enabled producing reliable weight-length dependencies for males and females by season and specify Bertalanffy growth equation parameters. Mean value of natural mortality rate was estimated at 0.55.

The Status of the Champsocephalus gunnari Stock in the South Georgia Area M. Basson, J. Beddington (United Kingdom) and W. Ślósarczyk (Poland)
Resumen:
This study focuses on the Chamsocephahus gunnari stock around South Georgia. The principle aims are, first, to assess current and past biomass and recruitment levels and, second, to analyse the relationship between the spawning stock and number of recruits. A conventional VPA and an ad hoc tuning method are used to estimate biomass levels and fishing mortality for the period 1971/72 to 1988/89 Read More
